Since 1987 infections with Salmonella enteritidis in poultry are increasing worldwide. There has been simultaneous increase in the number of human food poisoning cases associated with consumption of contaminated poultry meat and eggs. Until the age of one week chicks are very sensitive to infection with S. enteritidis, resulting in clinical symptoms and mortality. In the laying hen the ovarium and oviduct are predilection sites for S. enteritidis. Some animals become carriers after the acute stage of the disease. Diagnosis of infection can be made through bacteriological or serological examination. Vaccines, probiotics, certain carbohydrates and short chain fatty acids can partially protect chickens against the infection. The result of antibiotic treatment of infections with S. enteritidis is uncertain. Certain antibiotic treatments even may increase the severity of Salmonella infections in poultry. With the intention to eradicate infections with S. enteritidis and S. typhimurium in poultry, the European Union will introduce a monitoring and eradication program for the parent stock in the near future.
